Generally solar water heaters require minimal maintenance. However it would be good to take care of the system to ensure that it lasts longer. Kamlesh Sancheti, Head of Project Sales, Racold Thermo Private Limited, gives simple maintenance tips.

1. Periodic maintenance of solar water heaters is necessary every 3 to 5 years. Check for any kind of leakage in the pipes, tank, panels, etc as leakage is very common in these areas. Also, you need to check for loose wire connections and wires. Ensure that the panels are kept dust-free. If you find any crack in the insulation, see to it that it is replaced immediately.

Racold’s Alpha range of solar water heaters use high energy absorption vacuum tube of over 1800-mm length, which ensures optimum energy absorption and high efficiency.

2. Constant flow of water in the system leads to corrosion of heaters which, in turn, leads to the failure of solar water heaters.To keep the heater remain rust-free for longer period of time, dry it out when it is not in use. Freezing is another phenomenon that occurs in extremely cold climate. This affects the functioning of solar water heaters. Drain the collectors and pipes regularly so that the heaters don’t freeze.

3. Vegetation growth and dust accumulated on the collectors can become a cause of concern due to its continuous usage. Therefore, it needs to be cleaned regularly.

4. If there are any plumbing issues, contact your manufacturer or local service provider to sort the problem effectively.

5. In case of hard water, scale deposits will be observed in the collectors. These can be descaled with the help of acids.

6. To prevent erosion, the exposed surfaces should be painted or redone after 2 or 3 years. Also, if there is any broken glass, ensure that it is replaced by the manufacturer, if under warranty.
